Mercedes-Benz EQS 400 Recommended Charge Level
The Mercedes-Benz EQS 400 uses an NMC battery. The typical recommended charge limit is 80% to 90% for daily use and only charge to 100% for longer trips.
The recommended charge limit for NMC batteries is due to higher degradation risk from a higher state of charge.
Check your owners manual for specific recommendations for the Mercedes-Benz EQS 400.
